Application filed June 10, 1914 Serial No. 844,210.

To all whom it may concern:

Be it known that I, RUssELL T. WING, a citizen of the United States,residing at St. Cloud, in the State of Minnesota, have invented certainnew and useful Improvements in Fountain-. Pens, of which the followingis aspecifiuseful improvements in fountain pens having for its objectamong others to provide a simple, durable, efilcient and inexpensive penin which the pen point is so constructed essential features stitutingwhat may as to be practically proof against bending or breaking inordinary accidents, such as catching in writing or from such shocks asit would receive inaccidentally dropping it to'the floor,

of a perfect flowing fountain pen of the quill type.

A'furtherfobject is to provide means conbe termed an internal governorconstructed to take care of the overflow within the head of-the pen.This is attained. by providing a capillary cavity or holder, so formedthat the narrow end of the cavity will be n communication with the inkin the well,

the forward and larger end being left open ,to the air, the cavity beingtapered, all for a purpose which will hereinafter appear. I dispose thespring portion of the nibs near I the rear of the point and back in thehead of the pen, the forward portion of the point having its nibs madestiff and to withstand shocks, and finally tapered to a suitable writingtip, the nibs' being restricted in their separation or parting mpveznentby the surrounding head. piece.

Other objects and'advantagess of the invention' will hereinafter appearand the novel features thereof will be particularly pointed out in theappended claims.-.

The invention, clearly illustrated in I the accompanying with thenumerals of reference marked thereon, form a part of this specification,and in which-- i Figure 1 is an enlarged longitudinalsece point-endportion.

Like numerals of reference indicate like parts throughout the difl'erentviews.

Referringto the drawings, 1 designates a tubular holder of any ,suitablematerial, such as hard or vulcanized servoir for end with internal screwthreads, as at 2, for the detachable reception of the screw-threadedplug 3 which, in'turn, is ezrteriorly thre'aded as at 4, for thedetachable engagement of the cap 5 in the usual manner. The holder 1 andthe plug 3 may be all in onepiece, and for this reason the plug andholder throughout the specification will be termed the holder. Theforward end of this holder Ivlvhich shows a screw plug will betermed theead.

My invention resides inthe construction of the pen itself, which is madeof suitable metal and comprises the tubular portion 6, the nibs- 15 andthe spring portion 7 as shown. The body portion 10 (called the inclosedportion of the nibs) is longitudinally slitted, as seen at 14, fromthetubular portion 6 to the end or tip. These nibs are made stifi' andstrong toward the forward portion. At the rear, adjacent to the tubularThe said upper surface is disposed on a I plane oblique to thelongitudinal axis of-the tubular portion 6 and in a plane s'pbstantiallyparallel with the body portion 10, forming thereby a shoulder 19 that ispreferably rearward]. inclined relatively to the points, and provides 1nconjunction with t e upper surface of the body .portion and the adjacentwall of the plug -3 a chamber 13.; At this point itself serves to takeup the ink which might collect on the rapid closing of the nibs.

When the point is placed in the head as shown in Fig. 1, two cavitiesare formed by reason of the shaping of the inclosed portions of thenibs. The upper side of the inclosed portion of the nibs as well as'thelower side, are inclined as at 11 and 8, form ing the cavity 13 on theupper side and the passage 12 on the lower side. The passage 12communicates directly with the tubular portion, placing the ink in thewell practically in direct contact with the nibs. The

under and lower end of the inclosed portion of the nibs practicallyrests on the wall of the head as at 9.

By making the pen with the large opening for the ink where the ink flowsfrom the well to the point, the nibs are ractically directly in contactwith the ink in the well or reservoir 1. The air gains access to thereservoir or well by working under the nibs in writing. As the sides ofthe inclosed portion of the body 10 at 17 17 touch or nearly touch theinner walls of the heador plug, they form the cavity 13 above describedon the upper side of the pen to the rear of the nibs; the ink from thereservoir or well is retarded from vpassing into this cavity, bycapillary attraction, except slightly into its narrower end. It is to beunderstood that the size of the hole in the tubular portion may be smallor large, according to the quality of the pen. By havmg the pointdirectly in contact with the ink in the well, the ink is always at thepoint and does not depend upon the capillary attraction of any feedarrangementfor the flow of the ink.

In use, the chamber 13 takes care of the, ink flow entirely. An evenflow is obtained at all times, since a small amount of liquid in atapering cavity will always seek the narrower end, and as the narrowerend is at 18, see-Fig. 1, then if the ink' artially filled the chamber13 n writing t e ink would not remain at 19, the larger end of thetapering chamber, but would flow back to near the point 18 as long asused until air rises inthe well, passing around the nibs, and more inkcomes down, maintaining a constant level of ink 'in the governing cavity13 as long as the pen is used. It 1s to be noted that the forward end ofthe chamber 13 is left open to the air which is done to prevent a filmof ink from collecting at the point 19, which might happen if this werenot done, and to allow air to play freely back and forth in the chamber13 as the ink pressure in the well may vary, forcing the ink into thechamber 13 at different levels. film of ink at this point 19 would causeink to be expelled instead of air, from the chamber 13, and thus resultin a direct overflow of ink on the tip of the pen if there wereanyexpansion of the air in the reservoir 1.

From the above it will be seen that I have devised a novel form offountain pen caable of manufacture at small cost, embodymg but few partsand those readily assembled or separated when desired, and while thestructural embodiment of the invention as hereinbefore disclosed is what1 at the present time consider preferable, it is evident that the sameis subject to changes,

variations and modifications in details, proportion of parts, etc., and1 therefore, do

not intend to restrict myself to the exactconstruction herein disclosed,but reserve the right'to make such changes, variations and modificationsas come properly within the scope of the protection prayed.

Briefly described, I have provided a fountain pen having a suitable typeof reservoir 1 with a pen section 3 at one end thereof, inwhich pensection there is arranged a combined pen and feeder which has a tubularmouth portion 6 opening into the reservoir and from which extends a pairof parallel nib shanks or necks 1717 having a generally inclineddirection from the upper rear portion of the mouth down to the lowerfront end of the pen section on which the ends of the shanks 17 areprovided with.

nibs 1515 disposed wholly beyond the end of the pen section. Preferablythe exterior contour of the neck sections 17-17 when these are inrelatively closed position, as shown in Fig. 3, is such as to form abovethe top surface of the shank a chamber or pocket 13 which tapers gentlyfrom the outer portion of the pen section to the rear,

portion above the' flexible and flattened parts '7 of theshanks 17, thusallowing the ink which'passes between the split line 14 of the shanks topass under capillary action into the rear portion of the chamber 13 inwhich the body of ink will collect and be retained during the writingaction of the pen nibs.

The operation of this pen structure-and the formations of the respectiveparts may be explained as follows: When the necks 10 swing down toposition :shown in Fig. 1 there is formed above the top thereof aninwardly contracting space in which ink is drawn and held by capillaryattraction. When the nibs 15' are applied to a surface for writing thenecks 1O spread apart and upward and ink then flows from the mouth I 6into the kerf and along the nibs to the of the necks theink will advanceand recede in the space 13 always receding toward the smaller end as thenib necks approach and the space 13 enlarges,

I have shown in this instance the mouth piece 6, the nib necks (orfeeders) l0 and the nibs 15 as being integrally formed.

What I claim as new is 1. In a fountain pen, a reservoir having a pensection and a combined pen and feed having nibs projecting wholly beyondthe pen section, the feed comprising a mouth end and a split shankmounted 1n the section and communicating with the reservoir and formingresilient portions connecting the mouth and the pen nibs and lying in a'generally inclined position within the pen section to form an outwardlyconvergent lower ink space and an upper outwardly flaring ink space, thesplit shank being movable toward and limited in movement by the interiorsurface ofthe pen sect-ion.

2. In a fountain pen, a reservoir and a gen section and a combined penand feed aving a mouth at its inner end opening into the reservoirresilient feed sections extending from the mouth inclosed by the pensection, and nibs, on the ends of the feed sections', projecting beyondthe pen section, the feed sections forming an inwardly contracting inkspace at"the1r upper surfaces below the pen section.

In testimony whereof I hereunto afix my signature in presence off twowitnesses,
